What factors will affect the use of the dust bag? Mainly by corrosion of acid gases, smoke and high temperature oxidation, moisture in the flue, flue gas by four factors.

1. The corrosion of acid gases. When burning high-sulfur coal while or without desulphurization of flue gas, sulphur oxides, nitrogen oxides concentrations are high,apart from the FT filter dust bag, and other chemical synthetic material will be damaged by corrosion, dust bag service life will be shortened.

2. Flue gas temperature. Bag filter is mainly used in industrial boilers, fluidized bedboilers, kilns and coal-fired power plant boiler flue gas dedusting. This type of flue gas temperatures are often higher, gas into dust when the temperature is generally about 100 ~ 300 ℃. So ordinary performance will be affected under this temperature, chemical fiber, then filter bag dust filter must be used with high temperatureresistant fiber materials.

3. Moisture in the flue gas. Operating at high temperatures, when when the dust content in the flue gas of more than 25%, dust will produce easy to stick bag, blockbag, hydrolysis resistance of the material is not high, hydrolysis will damage filter.

4. Oxidation of flue gas. Dust bag has some oxidation of the smoke, because oxygen in the air 21%, coupled with the flue gas temperature is very high, so the dust bag will suffer at work, if you want to avoid this, choose something that have antioxidant effects filter dust bag.
